a full, clear, and exact description.V

My 'invention relates to covers, and particularly to covers for closing the openings in the top of ice cream cabinets rovided the ice cream receptacles disposed within the cabi net, -and theprincipal object of my invention is to provide a new and improved cover of this type. In the drawings accompanying this specification and forming apart thereof I have shown, for purposes of illustration, one form which my invention may assume; In these drawings:

Figure 1 is a top plan view of this lillustrative embodiment of my invention, while Figure 2 is a section on the line 2 2 of -Figure 1.

The cover herein shown comprises a metallic upper plate 11 and a metalliclower plate 12 turned over -at their edges to emrace an annular spacing member 13 arranged to cooperate with the central spacing member 14 to maintainA the plates 11 and A12 spaced apart to provide a closed space 15 for the reception 4of the heat insulating material 16. The spacing members 13 and- 14 may be formed of any desired material,

f' particularly wood, rubber, lor compositions,

but are herein shown as formed of wood. '.lhe plates 11 and 12, thespacing members 13 and 14, and the insulating material 16, are all maintained in assembled relation by means of a single bolt 17 having its head 18 in engagement with the lower face of the lower plate 12, passing` upwardly through a central aperture inthe lower plate 12, a central aperture in the space 14, and a central aperture in the upper plate 11, and screw threaded at lits upper end 19 to engage the coo erating threads of a metal sleeve 20 embeddp ed in a knob 21 etfectiveboth as ahandle for lifting `the cover and acting as a nut for the bolt 17, and maintained against rotation by means of a pin 22 extending upwardly into the knob 21 through an eccentric aperture in the top plate 11.

The engagement of the'cover with the adjacent surface is cushioned by means of a rubber ring 23 disposed in a groove 2l in the exterior face of the annularspacing member 13.

From the above description it will be obvious to those skilled in the art that I have provided a new and improved cover.

In addition, it will also be obvious to those skilled in the art that the particular embodiment of my invention herein shown and described may be variously changed and modified without sacrificing the advantages of my invention Aor departing from the spirit thereof, and it will therefore be understood that this disclosure is illustrative only and that my invention is not limited thereto.

I claim:

1. Acover, for an opening in the top ot an ice cream cabinet affording access to the interior ot' an ice cream receptacle therebelow, comprising a top plate, a bottom plate, an annular spacer separating said plates adjacent the periphery thereof, a circular central spacer separating said platesl centrally thereof, heat insulating material lin the chamber thus formed, and tie means connecting said plates together in such spared relation. I u
